Channel Control Section

1GAIN Control

Adjusts the input signal level.
To get the best balance between the S/N ratio and the
dynamic range, adjust the level so that the PEAK
indicator (2) comes on only at about maximum input
level.
The –60 to –16 scale indicates the MIC input adjustment
level. The –34 to +10 scale indicates the LINE input
adjustment level.

2PEAK Indicator

Detects the peak level of the post-EQ signal, and lights
up red when the level reaches 3 dB below the clipping
level. For XLR-equipped stereo input channels (5/6 and
7/8), detects both post-EQ and post-mic-amp peak
levels, and lights red if either of these levels reaches 3
dB below the clipping level.
nWhen the level of an input signal exceeds the level that
can be handled by the mixer’s head amp or equalizer,
distortion and noise will result. The PEAK indicators are
used to visually check the signal level to ensure no
overload occurs.

3 Switch (High Pass Filter)

This switch toggles the HPF on or off. To turn the HPF on,
press the switch in ( ). The HPF cuts frequencies
below 80 Hz. (But note that regardless of the switch
setting, the mixer does not apply this HPF to the line
inputs of stereo input channels.)

4Equalizer (HIGH, MID, and LOW)

This three-band equalizer adjusts the channel’s high,
mid, and low frequency bands. Setting the knob to the
position produces a flat frequency response. Turning the
knob to the right boosts the corresponding frequency
band, while turning to the left attenuates the band. The
following table shows the EQ type, base frequency, and
maximum cut/boost for each of the three bands.
nThe equalizer can be used to boost or cut specific
frequency bands, allowing the tone of the sound to be
shaped as required by the mix.
